Patent JP-H08321728-A (JP)
Title: Drive circuit
Inventor: YUKITA MASAHIRO
IPC: H03F3/213
Filed: 1995-05-25
Abstract: PURPOSE: To suppress distortion such as ringing independently of an externally mounted circuit by providing a circuit extracting a constant current from an output terminal operated just before an output operation is saturated. CONSTITUTION: When an output voltage Vo at an output terminal 21 to which an inductive load 22 such as a speaker of a drive circuit 1A exceeds a prescribed threshold voltage Vth, a prescribed current is extracted from the output terminal 21 by a constant current circuit 31 for this time only. Thus, even when a saturation where the current absorption by an output operation of the drive circuit 1A is not normally conducted takes place, generation of a transient abnormal voltage is prevented at the output terminal 21. Thus, even when an output voltage is fully swung up to the saturation level to obtain a high output, distortion such as ringing is effectively suppressed independently of an externally mounted snubber circuit.

Under this condition the thin membrane 12 has directivity so that the critical current density can be increased, resulting in generation of a large electric current.

Filed: 1989-05-19
Abstract: PURPOSE:To momently obtain a picture of desired magnification without trouble some operation like fine adjustment of a zoom lens by changing the sampling period of a taken-in input picture signal to expand/reduce the picture.

Title: Composite short-circuit testing circuit
Inventor: KAMEI KENJI
IPC: G01R31/327
Filed: 1991-05-30
Abstract: PURPOSE:To prevent transitional recovery voltage of an electric powder source circuit after current break from affecting on a test breaker by connecting an auxiliary breaker to both terminals of the test breaker in series and carrying out current break and voltage application at different time. CONSTITUTION:The time short-circuit current I1 break occurs is set to be T0. At the time T1 immediate before the time, electric charge of a capacitor 6 is discharged by a starting gap 7. Due to this, high frequency current I2 is generated and current I1 running in a test breaker 4 is overlaid with the current. The current I1 is shut at the time T0 and only the current I2 runs in the breaker 4 and an auxiliary breaker 5. The current I2 is shut at the time T2 after half- wave since the time T0 and transitional recovery voltage occurs at the point A where the breaker 4 is connected. Next, the electric charge of a capacitor 12 is discharged by a starting gap 13 at the time T3 after the current 12 break. Due to the discharge, transitional recovery voltage occurs at the point B where the breaker 4 is connected. Consequently, the voltage difference between the voltage at the point A and the voltage at the point B is applied to both terminals of the breaker 4.

Filed: 1990-05-17
Abstract: PURPOSE:To obtain a multifunction and multifocus shutter device which has high quality at low cost by performing the driving of a photographing lens to each focusing position and driving for a focusing action at each focusing position through a single action. CONSTITUTION:When a sun gear 31 is rotated counterclockwise, for example, planet gears 32-34 also revolve in the same direction and the 1st planet gear 32 abuts on and meshes with a gear 26 for driving a lens. In such a case, the gear 26 is on the revolution orbit of the planet gear and the revolution of the entire planet is prevented by meshing of the gears 32 and 26. Then, the rotation of the gear 31 all becomes the rotation of the planet and transmitted to the gear 26. When the lens is driven and reaches the desired focusing position, for example, a W position first, the focusing action based on the distance information of an object is performed at this position. The multifunction and multifocus shutter device which has high quality and is inexpensive and in which the switching of focus and the focusing action at each focusing position are performed by a single driving source 26 is obtained.
